T 0 all whom it may concern:

lie it known that l, CHARM-1s FRANCIS Jnxkixs, citizen of the United States, residing at \Vashington, in the District of Go hnnbia, have invented certain new and use to] improvements in 'lreating laper liottlcs, ol' which the following is a specil'ication. rel'erence being had therein to the ac- :ompan \jing drawing. I I Recently, ])ttl'tllllll-(t();ll6(l paper bottles have been used more or less extensively for milk, the intent being that no bottle shall be used but once. Practically, such bottles are useless if the cost exceeds a very low maximum, audit is nearly indispensable that the bottles be convenient, and quite indispensable that they be as perfectly sanitary as they can bemadc. These combined conditions make the prmluction ot satisfactory bottles ditiicult. and render every approach toward perfection. as well as the smallest reduction in cost. important.

Kl provide for waterproofing and sterilizing, wit houthandling the bottles, by, devices shown in the :u-com nmying drawings. in which,

Figure l is a side elevation oi the apparatus. Fig. 2 is an end elevation looking from the right in Flg. 1. Fig. is a \'ert1 cal section, showing on a larger scale devices seen near the middle oi Fig. 1. Fig. 4 is a partial enlarged \'ic\\' partly in secticui and corresponding nearly to a portion oi Fig. Fig. 5 is a plan view oi devices seen also in Figs. l. t. Fig. (3 is an enlarged plan view o'l' devices seen near the left side of l ig. t. Fig. 7 is a cross section oi the correspomlingly lettered tube of Fig. 1.

in these ligurcs. represents tpright ends of a frame which are connected by four parallel rods l3, ii the. upper pair of which extend outward to any desired distance, beingsupported at their outer ends in any suitable way, as by standards in the main frame is supported a parailin tank l) heated by burners I or tn. like,

- and in this is placed a downwardiy curved tube l) which is upwardly open near its ends. Above the tube and its plane are mounted belt pulleys l carrying an endless belt; F provided at intervals with outwardlyuextending wings F and having its lower fold inside the tube D. The bel'tis driven in any suitable way, as by a. motor G, belt G and pulley G on the shaft G of one of the pulleys F. Open cylindrical paper bottles H to be parattined are placed in an inclined transverse chute I which do livers them in the open end portion 1) of the tube 1) as shown in Figs. 2, t, 5, the

bottoms of the bottles being turned toward the body of the tube. The foremost bottle is caught by one of the wings F and forced downward into the hot paraflin which enters the tube through suitable openings D (Fig. 7), and as soon as the mouth of the bottle passes below the level of the liquid, the latter flows in expelling the air, which owing to the upward inclination of the bottle at this time can never be imprisoned to prevent the liquid from reaching every part of the interior surface. As the advancing bottle rises, from the bath, toward the opposite end ot the tube, all the parafiin is discharged. The lower side of this end of the tube is bent: downward at I) (Fig. 3) and terminates in an inclined apron-like portion 1) terminating a little abov v a carrier belt K mounted upon pulleys K driven in any suitable way as by a belt K from the motor, and supported by the rods B which are connected by members B to form a. rigid irame. the wings F discharge the bottles upon the inclined apron the bottles slide downward and gently tilt to erect position upon the conveyer belt which carries them through a sterilizing chamber M, of any desired length, which is highly heated by means of a gas burning device at N, or by other suitable means. After leaving the sterilizer, they pass onward in thcopen air for such distance that. the paraffin has time to cool and are finally discharged at the end of the conveyer.

To prevent. possible accidents in 'leeding the bottles to the immersing tube, the foremost bottle in the chute rests against, a light spring 0, Fig. 5, which is pushed aside by the tlflVtU'lClDg Wing which advances the bottle into the tube. This spring engages the bottle near its endso that. the bottle usually tilts, as shown, so that the wing strikes the end squarely and moves the bottle in the direction of the axial lineot the latter. If for any cause the bottomof the bottle should catch the edge of the chute at P, this edge yields, since the lower portion of this side of the chute is held in place by a light spring hinge Q, and is readily swungout against an inclined lip R upon the tube, the lip guiding the advancing bottle uninjured into the tube.

\Vhat I claim is:

1. The combination with a receptacle for liquid paraffin, of a conveyer adjacent thereto, means for submerging open bottles in the parafiin and withdrawing and emptychamber, a traveling conveyer arranged to carry material through said chamber, and automatic means for submerging open bottles in the parafiin, emptying them, and reversing and delivering them in erect position to said conveyer'.

4%. The combination with a receptacle for paraifin and means for keeping paraffin therein in a liquid state, of an open way having its middle bent downward and sub-- merged in the parafiin, an endless belt pro vided with wings and having one fold guided in said Way, means for driving the belt, and means for delivering an open bottle, with its axis parallel to the plane of said belt, in

versely therein, of a transversely moving belt provided with wings in position to strike the ends, respectively, of the foremost bottles in the chute and remove them in succession, substantially as set forth.

7. The combination with an inclined chute, adapted for the descent therein of a series of transverse bottles, a transversely moving belt proyided with wings in position to push the foremost bottles successively from the chute, and a spring in position to limit the descent of the foremost bottle in the chute.

S. The combination with a chute adapted for guiding a series of bottles placed transversely therein, of means for moving the bottles of the series in succession laterally out of the chute, one guiding side of the chute being adapted to spring aside when pressed by an outgoing bottle, substantially as set forth.

In" testimony whereof I afiix my signature in presence of two witnesses.
